WatchParty

An extension that lets you watch your favourite Movies, TV Series, and much more with your friends and family.
It works on any of your streaming services like Netflix, Prime Video, Hulu, YouTube, or any other.

ONLY THE HOST IS REQUIRED TO HAVE A SUBSCRIPTION

Installation and Usage

Chrome Extension

Highly recommended to Use Chromium

• Go to chrome://extensions
• Then click Load Unpacked
• Go to WatchParty/extension in the browse folder and select
• Enable the extension if disabled and then pin the extension to the title bar
• Development:
  • The content.js logs will be displayed in the website console itself
  • The logs of popup.js can be shown by: Right Click > Inspect pop-up > Console

Backend and Frontend

• run npm install then npm start to run the application. Then open your browser at http://localhost:3016 or your own defined port/url in the config file.
• (optional) edit the src/config.js file according to your needs and replace the ssl/key.pem ssl/cert.pem certificates with your own.

Currently, for running on websites,

• Type chrome://settings/content/insecureContent in chrome URL bar.
• Select Add
• Now add the base Url of the website.
  • Ex for youtube: [*.]youtube.com
• Then start streaming on that website using the extension

Known issues

• There is a de-sync in the audio-video stream from the host
• When directly sharing a video, and either its src changes (ex. youtube ads) or the video ends, transmission freezes
• Extension popup closes when share popup comes, thus link not copied.
• Site on accessible even from within the same network
• Still on HTTP, so extension can't be run on websites directly.
• Netflix seekto doesn't seem to work.
• Noise in audio when stream changed multiple times

Deployment

• in config.js replace the announcedIP with your public IP address of the server (important) and modify the port you want to serve it in.
• add firewall rules of the port of the webpage (default 3016) and the RTC connections (default UDP 10000-10100) for the machine.

Note :

• Best to run the project on a Linux system as the mediasoup installation could have issues by installing on windows. If you have a windows system consider installing WSL to be able to run it.
• installing wsl on windows 10
